New Delhi: Delhi Chief Minister Arvind Kejriwal today urged Prime Minister Narendra Modi to 'apologize to the nation' for allowing a Pakistani team to probe the terror attack on the Pathankot IAF base.

Amid Pakistani media reports that the Pakistani investigators had concluded that the January 2 attack was staged by India, Kejriwal insisted that there had been some 'deal' between the BJP and Islamabad.

"What's the deal, we are unable to understand," the Aam Aadmi Party (AAP) leader said at a media meet. "What was the need to invite the very people who attacked the base to investigate the attack?"Kejriwal said there was mass anger over the PM Modi government's decision to allow a Pakistani Joint Investigation Team (JIT) to visit the Pathankot base and also hold talks with the National Investigation Agency (NIA).

He recalled that PM Modi used to thunder at election rallies during the Lok Sabha election of 2014 that one had to be stern with Pakistan and that sending 'love letters' to Islamabad won't help.
